One the the most helpful tools in a tradesman"s toolbox is the usual tape measure. Let"s see just how to review a ice measure.
You are watching: Where is 17/32 on a tape measure
The ice measure can be significant with us or English measurements (feet and also inches), metric dimensions (meters and also parts the meters: centimeters, millimeters, etc) or both shared on the exact same tape. Most tape measures have actually common aspects to have the ability to use them easily. Many US tape measures have actually both inches and foot marks. Notice that the 16", 32", 48", 64", etc. Are significant differently 보다 the other inch markers. Part tape actions have little black arrows or pointers through a box approximately the number, various other tape measures have these numbers highlighted in red. These numbers describe the 16" centers for laying out studs and joists. Most carpenters have actually the 16" centers memorized as much as 8", yet a tiny help on the tape measure is well received as soon as you acquire to 128". And also the 16" marks, an alert a black color diamond note every 19.2 inches, likewise called the black color truss mark. The was put on the ice cream measure initially to clues the on-center position of residential roof trusses. Quite than put 6 trusses in 8", every 16", they conserved a truss every sheet of plywood by dispersing them out. We don"t use this place today through our trusses, which are frequently designed because that 24 inch centers.
When you read a tape measure a small knowledge of mathematics is needed. We know that 1/2 is the exact same as 4/8, 8/16, 16/32, etc. We could refer to the 1/2" note as the 16/32" mark but we usually use the easiest numbers possible. Because we understand that 16/32 is 1/2, when looking for 15/32" on the ice cream measure, because that example, it is the first 32nd before the 1/2" mark.
Actually, in the field a carpenter refers to a 32nd together plus or minus a major fraction. Because that instance, 13/32 is 1/32 much less than 14/32 or 7/16, so us say "7/16 minus" and 11/32 is 1/32 much more than 10/32 or 5/16, so we say "5/16 plus". This is a fast means of analysis the tape measure up on the job once taking a measure up of other to reduced it come fit. What you must do is memorize the common fractions under to sixteenths.
Here they are:
1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16 and also the inch mark.
How to review a ice Measure
We use thirty-seconds in the stairway calculator, and also other instances like that, simply for accuracy due to the fact that when you"re cutting 16 stair risers, if you are 1/16th inch the end on every stair, you room out a entirety inch at the end. Also being 1/32" out provides an error the 1/2"!
